I hired a survey company to do a survey to determine my property lines during escrow. The Title inspection report showed a possible encroachment of a backyard wall onto neighbor's property. We hired a survey company that reported no more than 3 feet encroachment. The neighbor's survey shows a 10 feet encroachment. Note that house is on a curved (cul de sac) street, and the wall has been there 50 years. How do i determine, prior to the quitet title hearing, which survey is more accurate? Are there potential valid reasons why my survey is correct and the neighbor's survey is wrong? What do i do if i lose in court because the survey i paid for was inaccurate and/or used incorrect methods?
